Michigan grinds past Penn State to stay unbeaten despite Jim Harbaugh ban

• No 2 Michigan beat No 19 Penn State 24-15 despite suspension
• Wolverines run ball on 32 straight plays in dominant showing
• College football's sign-stealing scandal explained

With Jim Harbaugh banned by the Big Ten Conference, JJ McCarthy, Blake Corum and No 2 Michigan played unfazed by a scandal that has hounded the program for weeks - and their toughest opponent yet - grinding past No 9 Penn State 24-15 on Saturday.

Corum ran for 145 yards and two touchdowns, McCarthy made few key plays with his arms and legs and the Wolverines (10-0, 7-0, No 3 CFP) improved to 3-0 since it was revealed the program was under NCAA investigation for a sign-stealing scheme.
